[0028] The embodiment of the utility model provides a large-diameter spray-type wound pre-buried insulation pipe rapid cooling spraying device.

[0029] Please refer to Figure 1 , including a workbench 1 and a fixed frame 2 fixed on the top surface of the workbench 1. The fixed frame 2 provides support and fixation effects for the operation of the spraying mechanism 3. A servo motor is installed outside the fixed frame 2. The servo motor is a prior art and will not be elaborated in this application.

[0030] Please refer to Figure 1 and Figure 4, above the workbench 1, there is a spraying and winding heat preservation pipe 4. On the top surface of the workbench 1, two stabilizing frames 5 are fixedly connected. The stabilizing frames 5 are adapted to the spraying and winding heat preservation pipe 4. The stabilizing frames 5 can stably clamp the spraying and winding heat preservation pipe 4, so that the spraying and winding heat preservation pipe 4 can remain stable during the spraying operation, and prevent the spraying and winding heat preservation pipe 4 from rotating during the spraying process, which may damage the heat preservation layer on its surface.

[0031] A set of card slots are opened on the inner wall of each stabilizing frame 5. Inside each card slot, a smooth roller 6 is rotatably connected. The smooth roller 6 slightly protrudes from the inner wall surface of the stabilizing frame 5, which is convenient for the staff to pull the spraying and winding heat preservation pipe 4 in the stabilizing frame 5. The smooth roller 6 can prevent friction between the stabilizing frame 5 and the spraying and winding heat preservation pipe 4. The surface of the smooth roller 6 is treated with smoothness to avoid large friction between the spraying and winding heat preservation pipe 4 and the smooth roller 6 when the spraying and winding heat preservation pipe 4 moves in the stabilizing frame 5, which may damage the heat preservation layer on the surface of the spraying and winding heat preservation pipe 4.

[0032] Please refer to Figure 1 and Figure 2 , the bottom surface of the workbench 1 is fixedly communicated with a water storage tank 7. An extraction pump 8 is fixedly installed outside the water storage tank 7. The extraction pump 8 is an existing technology and will not be elaborated too much in this application. Through the setting of the extraction pump 8, the water stored inside the water storage tank 7 can be pumped into the water delivery hose 9, so as to facilitate the subsequent spray head 302 to spray the spraying and winding heat preservation pipe 4. A water body cooling device can be installed inside the water storage tank 7 according to actual needs.

[0033] The end of the extraction pump 8 is fixedly communicated with a water delivery hose 9. The other end of the water delivery hose 9 is fixedly communicated with the spray support plate 301. The water delivery hose 9 is made of soft plastic material, and its length is sufficient to move according to the movement of the spray support plate 301 without hindering the movement of the spray support plate 301.

[0034] The top surface of the workbench 1 is fixedly connected with a water collecting tank 10. A flowing water groove 11 is opened on the inner bottom wall of the water collecting tank 10. The flowing water groove 11 is communicated with the top surface of the water storage tank 7, which is convenient for the water to flow into the water storage tank 7. Through the setting of the water collecting tank 10 and the flowing water groove 11, the water used in the spraying operation can be collected into the water collecting tank 10 and then stored in the water storage tank 7 again through the flowing water groove 11, which is convenient for subsequent spraying operations again, realizing the reuse of water resources and reducing the waste of water resources.

[0035] Please refer to Figure 1 and Figure 3, there are two spraying mechanisms 3 for spraying operations inside the fixing frame 2; the spraying mechanism 3 includes a spraying support plate 301, which is an arc-shaped semi-ring, and its radian is adapted to the sprayed and wound heat-insulating pipe 4. A water pipe communicating with the water delivery hose 9 is installed in the spraying support plate 301, and it can transport the water conveyed in the water delivery hose 9 to each spray head 302, facilitating the subsequent spraying operation of the spray head 302 on the sprayed and wound heat-insulating pipe 4.

[0036] A group of spray heads 302 evenly distributed on the surface of the spraying support plate 301 are fixedly installed inside the spraying support plate 301. The spray heads 302 are circumferentially arranged around the sprayed and wound heat-insulating pipe 4, and can spray the sprayed and wound heat-insulating pipe 4 in all directions, improving the spraying angle of the device and enabling each position of the sprayed and wound heat-insulating pipe 4 to receive the same cooling effect.

[0037] Drying fans 303 are fixedly installed on both side surfaces of the spraying support plate 301. Through the setting of the drying fans 303, the surface of the sprayed and wound heat-insulating pipe 4 after spraying can be air-dried, removing the remaining water droplets on the surface of the sprayed and wound heat-insulating pipe 4, reducing the time required for placing and drying, and improving the cooling efficiency of the device.

[0038] Please refer to Figure 1 and Figure 3 , a protection box 304 is fixedly connected inside the fixing frame 2. A transmission screw rod 305 is rotatably connected inside the protection box 304. The connecting support rod 306 is slidably connected to the protection box 304. The transmission screw rod 305 penetrates through the protection box 304 and the workbench 1 and is rotatably connected to the protection box 304 and the workbench 1. The transmission screw rod 305 is fixedly connected to the output rotating shaft of the servo motor. When the servo motor is started, the transmission screw rod 305 will rotate accordingly. The rotation of the transmission screw rod 305 can drive the connecting support rod 306 to slide inside the protection box 304. The staff sets the forward and reverse rotation program of the servo motor according to the length of the transmission screw rod 305, and the connecting support rod 306 can be made to slide reciprocally.

[0039] A connecting support rod 306 is threadedly connected to the outer surface of the transmission screw rod 305. One end of the connecting support rod 306 away from the transmission screw rod 305 is fixedly connected to the spraying support plate 301. The reciprocating sliding of the connecting support rod 306 can drive the spraying support plate 301 to move back and forth inside the fixing frame 2, thereby driving the spray head 302 to spray different positions of the sprayed and wound heat-insulating pipe 4, improving the spraying range of the device, and avoiding the problem of pits appearing on the local surface of the sprayed and wound heat-insulating pipe 4 under long-term spraying.

[0040] Working principle: The staff first place the position of the spraying and winding heat preservation pipe 4 that needs to be sprayed in the fixing frame 2, and then start the servo motor and the water pump 8. The start of the motor can drive the transmission screw rod 305 to rotate, and the rotation of the transmission screw rod 305 drives the connecting support rod 306 to move. The movement of the connecting support rod 306 can drive the spraying support plate 301 to reciprocate inside the fixing frame 2. The start of the water pump 8 can transport the water stored in the water storage tank 7 to the spray head 302 through the water delivery hose 9, so that the spray head 302 sprays the surface of the spraying and winding heat preservation pipe 4. After the spraying is completed, the water pump 8 is turned off, and the drying fan 303 is started. Driven by the spraying support plate 301, the drying fan 303 blows and dries the surface of the spraying and winding heat preservation pipe 4, improving the efficiency of the device for cooling the spraying and winding heat preservation pipe 4.
